GPIO Pins input

[BoonDogs]

I want to set up one of the GPIO pins on my pi, so that when an external relay closes, using the 3.3 volts from the Pi, it triggers a background sequence (or an audio file of background sequence isn't possible) any ideas on the scripting? Which pins do I connect the wires from the relay to?

The hookup info is on the GPIO input help screen. Hit 'F1' or click the help link under the right side of the menu when you are on the GPIO input screen.

You need to create a script to start a playlist or effect sequence. Then you will create an Event to run the script, and finally setup the GPIO input to trigger the event.

You can use pretty much any GPIO pin you want, the list is on the GPIO input config page in FPP.
